Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a species with an endoxylic thallus and black, subglobose to tuberculate apothecia with a blue-green epihymenium reacting N+ red, and oblong to ellipsoid, simple to 1-septate ascospores; pycnidia usually present, black, containing short bacilliform mesoconidia; on decorticated wood in coniferous forests; widespread in Europe, but altogether rare, and only recorded from the Western Alps (Switzerland).
